The Schedule referred to` in these Lettera Patent and making part of the same.

To all whom it may conce/rn:

, patent for a description of the parts that areused with my improvement and for the details of the construction and operation of therbook-sewing machine.

In the before-named patent the folded and notched sheets of paper are laid upon a table, and Vthis table' rises as the table descends that receives the sewed sheets.

Needles are providedV with eyes near the point, and they stand in a roiv contiguous to the descending table so as to occupy the notches in the folded edges of the sheets, and these needlesreceive through their eyes the cords or bands that are drawn into the said notches as the pile of sewed sheets is raised up to. draw said pile oi the stationary needles.

The thread is laid into the fold of the sheetin front of' the needles by means of a traveling or reciprocating hook, and the sheet is folded over and pressed upon the pile ou the receiving-bed by means of litters or folders, as will more fully appear by reference to the 'said Letters Iatent.

In practice it is found that the long slender needles that are made use of, are lia-blc to bend and sonictimes to break under lthe pressure to which they are subjected, as the pile oi' sewed sheets is being forced down upon the receiving-table and along the said needies.

My present invention relatesto a device for supporting these needles and preventing them bending under the endwis'e pressure and strain to which they are subjected.

In the accompanying drawings-4 Figure 1 is an elevation of the receiving-table,.necdies, and supports;

Figure 2 is a transverse section at the linexaz; and Figure 3 is an inverted plan of the receiving-table and needle-supports. v

The receiving-table e is upon the standards f that contain rack-teeth, so that the table s moved by pinions, as' in aforesaid patent, or otherwise.

The hook g on the reciprocating bar h is illustrative oi" the correspondingly-mzu'ked parts in the aforev said patent, and being fully described therein do not require further explanation.

Upon the under side of the receiving-table e are bars with an undercut groove, ig, between them, rc-

ceiving the "heads of the bolt-s lc, which bolts pass .through elongated holes in the supporting-brackets l.

Each of these brackets lhas a groove at one edge for the needle nt, soas vto` support the needle below the table c and prevent said needle springing or bending. The platefD being contiguous to the needle, prevents the same 'springing away from the support l; hencf` the. needles are not as liablct'o be injured asin the machines heretofore. constructed.

'AThe supporting-brackets being secured by the bolt k, can be moved to any position corresponding to .that ot' the needles and their clamps.: These grooved s'upporting-brackets become guides that keep the needles 'in position for receiving the first sheets in commenc- Witnesses JAMES TinnuvenAsr, GEO.
